Description

Technical Field

[0001] This utility model relates to the field of magnetic material testing technology, specifically to a high-efficiency magnetization testing device for magnetic materials. Background Technology

[0002] Materials that can respond to a magnetic field in a certain way are called magnetic materials. Based on the strength of their magnetism in an external magnetic field, materials can be classified into diamagnetic, paramagnetic, ferromagnetic, antiferromagnetic, and ferrimagnetic materials. Most materials are diamagnetic or paramagnetic, and their response to external magnetic fields is relatively weak. Ferromagnetic and ferrimagnetic materials are strongly magnetic materials; the term "magnetic material" usually refers to strongly magnetic materials. For magnetic materials, magnetization curves and hysteresis loops are characteristic curves reflecting their basic magnetic properties. Ferromagnetic materials are generally composed of Fe, Co, Ni elements and their alloys, rare earth elements and their alloys, and some Mn compounds. Magnetic materials are generally classified into soft magnetic materials and hard magnetic materials according to their ease of magnetization.

[0003] In the production process of magnetic materials, the workpiece needs to be magnetized to make it magnetized. After the magnetization is completed, the magnetic material needs to be tested for magnetization to ensure the magnetization effect. The magnetization test needs to be performed using a magnetization test device.

[0004] Existing magnetization testing devices mostly use two clamps to hold toroidal magnetic materials, which can easily lead to unstable clamping, affecting the magnetization test results and reducing the testing efficiency. Therefore, there is an urgent need to design a more efficient magnetization testing device for magnetic materials to solve these problems. Utility Model Content

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-3 As shown in the figure, the present invention provides a high-efficiency magnetization testing device for magnetic materials, including a base 1 and a detector 10. A rotating mechanism 11 is provided on the upper side of the base 1, and a clamping mechanism 12 is provided on one side of the rotating mechanism 11. The clamping mechanism 12 includes a mounting frame 18 and an electric telescopic rod 19. The mounting frame 18 and the electric telescopic rod 19 are both located on one side of the rotating mechanism 11. Four sliding grooves 21 are opened on one side of the mounting frame 18. Sliding blocks 23 are slidably installed in the sliding grooves 21. An arc-shaped block 22 is fixedly installed on one side of the sliding block 23. A movable disk 20 is fixedly installed at the output end of the electric telescopic rod 19. A connecting rod 24 is provided between the movable disk 20 and the sliding block 23. The two ends of the connecting rod 24 are rotatably connected to the movable disk 20 and the sliding block 23, respectively. The electric telescopic rod 19 and the movable disk 20 are both located between the mounting frames 18.

[0024] Specifically, in this embodiment, annular magnetic material is fitted around the four arc-shaped blocks 22. Then, the electric telescopic rod 19 is activated, causing the moving disk 20 to move. The moving disk 20 pushes the connecting rod 24. Due to the limiting effect of the sliding block 23, when the moving disk 20 pushes the connecting rod 24, the connecting rod 24 can rotate outward. The outward rotation of the connecting rod 24 causes the sliding block 23 to move outward along the sliding groove 21. The outward movement of the sliding block 23 causes the arc-shaped blocks 22 to move outward. The outward movement of the arc-shaped blocks 22 can abut against the inner wall of the annular magnetic material. By the synchronous outward movement of the four arc-shaped blocks 22, the inner wall of the annular magnetic material is pressed against the inner wall. The contact mechanism can clamp the annular magnetic material tightly, achieving stable holding. To release the clamp, simply reverse the above steps. Each of the four arc-shaped blocks 22 is equipped with a rubber anti-slip pad, which further enhances the clamping effect of the annular magnetic material, thereby improving the stability and efficiency of the magnetization test. The detector 10 consists of a current sensor, a voltage sensor, and a data acquisition card. The current and voltage sensors detect the magnetization current and voltage of the magnetic material, and then the sensors convert the detected signals into electrical signals, which are then acquired and processed by the data acquisition card.

[0025] This utility model provides a high-efficiency magnetization testing device for magnetic materials. The rotating mechanism 11 includes a fixed frame 13 and a rotating disk 17. The fixed frame 13 is fixedly installed on the upper side of the base 1. A rotating groove is opened in the center of the fixed frame 13. The rotating disk 17 is rotatably installed in the rotating groove. A worm gear 14 is provided on one side of the rotating disk 17. A first drive motor 15 is fixedly installed on the upper side of the fixed frame 13. A worm 16 is fixedly installed at the output end of the first drive motor 15. The worm 16 meshes with the worm gear 14. The mounting frame 18 and the electric telescopic rod 19 are both fixedly installed on one side of the rotating disk 17.

[0026] In another embodiment of this utility model, the first drive motor 15 is started to drive the worm gear 16 to rotate. The rotation of the worm gear 16 can drive the worm wheel 14 to rotate, the rotation of the worm wheel 14 can drive the rotating disk 17 to rotate, the rotation of the rotating disk 17 can drive the clamping mechanism 12 to rotate, and thus drive the annular magnetic material to rotate. This allows the detector 10 to perform magnetization tests on different parts of the annular magnetic material, improving the convenience of magnetization tests on the magnetic material. The inner wall of the rotating groove is provided with an annular groove, and the rotating disk 17 is provided with an annular protrusion. The annular protrusion rotates in the annular groove, thus enabling the rotating disk 17 to rotate stably between the rotating grooves. The self-locking characteristics of the worm gear 16 and the worm wheel 14 can improve the stability of the rotating disk 17 after rotation.

[0027] This utility model provides a high-efficiency magnetization testing device for magnetic materials. A slide rail 2 is provided on the upper side of a base 1. A threaded rod 3 is rotatably mounted on the slide rail 2. A threaded slider 5 is threadedly mounted around the threaded rod 3. A second drive motor 4 is fixedly mounted on one side of the base 1. The output end of the second drive motor 4 is fixedly connected to one end of the threaded rod 3. A sliding shell 6 is fixedly mounted on the upper side of the threaded slider 5. A lead screw 7 is rotatably mounted inside the sliding shell 6. A third drive motor 8 is fixedly mounted on one end of the sliding shell 6. The output end of the third drive motor 8 is fixedly connected to one end of the lead screw 7. A support frame 9 is slidably mounted inside the sliding shell 6. The support frame 9 is threadedly connected to the lead screw 7. A detector 10 is fixedly mounted on one side of the support frame 9.

[0028] In another embodiment of this utility model, by starting the second drive motor 4 to drive the threaded rod 3 to rotate, the rotation of the threaded rod 3 can drive the threaded slider 5 to move, the movement of the threaded slider 5 can drive the sliding shell 6 to move longitudinally, the longitudinal movement of the sliding shell 6 can drive the support frame 9 and the detector 10 to move longitudinally. By starting the third drive motor 8 to drive the lead screw 7 to rotate, the rotation of the lead screw 7 can drive the support frame 9 to move laterally along the sliding shell 6, the lateral movement of the support frame 9 can drive the detector 10 to move laterally. This allows the operator to adjust the detector to a suitable position according to different needs, improving the convenience and practicality of the magnetization testing device.
